Abstract: An oxidation process in which a metal nitro complex transfers an oxygen atom from the nitro ligand to a substrate; especially such process conducted cyclically or catalytically using molecular oxygen as the oxygen source. Metal nitrosyl complex is formed as a coproduct together with an oxidation product of the substrate. In a cyclic process, nitrosyl ligand of the metal nitrosyl coproduct is reoxidized by molecular oxygen in presence of a monodentate base such as pyridine to nitro ligand; and the nitro complex, thus regenerated, can be used again to oxidize the substrate. In a catalytic process, using an activator such as a Lewis acid with alcohols or divalent palladium with olefins, elemental oxygen maintains a concentration of nitro ligand in the reaction mixture. In particular the metal is a Group VIII metal, especially cobalt and the ligand is saloph or tetraphenylporphyrin.

Abstract: An anhydride of a carboxybenzene is esterified in solution by a fluorinated alcohol, using N-methylpyrrolidone solvent. In particular, pyromellitic dianhydride in N-methylpyrrolidone solvent is esterified to the diester/diacid by 2-(n-perfluoroalkyl)ethanols having six to twelve carbon atoms in the perfluoroalkyl groups, and the reaction mixture containing the dissolved diester/diacid is admixed with an oxirane compound of the group ethylene oxide, epichlorohydrin and glycidol whereby the carboxyl groups are esterified in the N-methylpyrrolidone solvent by reaction with oxirane groups.

Abstract: A process for oxidizing organic substrates such as ketones and ethylenically unsaturated compounds. The substrate is contacted with aqueous hydrogen peroxide in a solution or in a two-phase liquid system, in the presence of a polymeric catalyst containing chemically bonded arsenic. This process can lead to lactones or hydroxy acids from cyclic ketones or to esters or mixtures of alcohol and carboxylic acid from open chain ketones. Unsaturated compounds afford epoxides and/or diols. Preparations of certain polymers substituted by arsenic groups, particularly from polystyrene, poly(vinylpyridine) and copolymers thereof, useful as catalysts in such oxidation process, are described. For example, polystyrene is brominated, bromine therein is replaced by lithium and the resulting lithiated polymer is converted into a polymer containing an arsenic group, such as arsono, --As(O)(OH).sub.2, as substituent group, by reaction with arsine triethoxide followed by oxidation and hydrolysis by aqueous hydrogen peroxide.

Abstract: A catalytic system for oxidation of organic compounds including olefins, cyclic ketones and secondary alcohols. Soluble peroxo or solid supported oxo or peroxo complexes of molybdenum or tungsten are used in the presence of hydrogen peroxide to effect the oxidation. The resulting products include lactones, hydroxy acids, ketoacids, hydroxy esters and ketoesters from cyclic ketones; ketones from secondary alcohols and polyols or derivatives thereof from allylic alcohols.

Abstract: As an additive imparting oil and water repellency, durable against laundering and abrasion, to PET fibers: a partially or fully acylated polyol, especially pentaerythritol, glycerol, hydroquinone or ethylene glycol, acylated with a phthalic or terephthalic monoester having a perfluorinated alkyl or alkoxyalkyl C.sub.2 to C.sub.20 radical, especially C.sub.5 to C.sub.10 n-alkyl or (CF.sub.2).sub.n OR.sub.f where R.sub.f is C.sub.1 to C.sub.6 perfluoroalkyl, especially perfluoroisopropyl and (CF.sub.2).sub.n is a straight chain C.sub.2 to C.sub.10 diradical.

Abstract: A process for oxidizing ketones with hydrogen peroxide. The ketone is contacted with the hydrogen peroxide in a buffered solution in the presence of an arsenic containing catalyst. This process can lead to lactones directly from cyclic ketones.

Abstract: Polycarboxybenzenes esterified with certain partially fluorinated alcohols and with hydroxyl-containing organic radicals such as 2-hydroxyethyl, glyceryl and chlorohydryl or bromohydryl, leaving no free carboxy groups, when incorporated with PET or nylon fibers as by contact in a liquid medium, these compounds concentrate at the fiber surface especially if the fiber is annealed (heated without abrading above its T.sub.g). A relatively durable oil and water repellency is thus imparted to the fiber; which durability can be enhanced by contacting said compound in situ in the fiber with a polyepoxide or polyisocyanate.Alternatively, partially fluorinated N,N-disubstituted amides, esterified also with the same above-cited hydroxyl-containing organic radicals, can be used. The resulting fibers can be dyed, after or together with said treatment imparting repellency.

Abstract: A process of reacting in the liquid phase a hexacoordinated ruthenium(II) complex with oxygen in the presence of a source of hydrogen ions under conditions forming hydrogen peroxide and the corresponding hexacoordinated ruthenium(III) complex and reacting the hexacoordinated ruthenium(III) complex with hydrogen sulfide to form elemental sulfur and regenerate the hexacoordinated ruthenium(II) complex, the hexacoordinated ruthenium(III) complex having a reduction potential of not more than +0.68. Five or six of the ligands of the ruthenium complexes are non-labile in both valence states.

Abstract: Fluorinated poly-(C.sub.2 to C.sub.10) alkylene polyamides (especially alpha, omega-triazaalkanes) in which the endmost nitrogen atoms are acylated by fluorinated carboxylic acid groups and an interior nitrogen atom is acylated by a dibasic acid moiety of the group consisting of (C.sub.4 to C.sub.14) alkane dioic acid moieties and the thiocarbonic acid moieties --C(.dbd.O)S-- and --CS.sub.2 --; wherein per the invention, a radical is terminally attached to the acylating dibasic acid moiety, of the group --CH.sub.2 CH.sub.2 OH, --CH.sub.2 CH(CH.sub.3)OH, --CH.sub.2 CH(OH)CH.sub.2 X (X being halogen or --CN), or ##STR1## The compounds are amphipathic, behaving like surfactants when incorporated with nylon. They are prepared by broadly known methods of producing esters and thioesters of acids. The stain resistance of fibers incorporating these compounds can be improved as to durability and at least partially restored after abrasion of the fiber, by annealing.

Abstract: A novel process is described for preparing low valent Group VIII metal hydrides, useful as catalysts in the hydrogenation of a large variety of organic compounds, in which a low valent Group VIII metal halide complex, such as (Ph.sub.3 P).sub.3 RhCl, is reacted with an alkali or alkaline earth metal alkylamide, such as LiN(CH.sub.3).sub.2, containing at least one alkyl group having an alkyl hydrogen atom in the beta position with respect to the metal atom. The metal alkylamide functions both as a dehalogenating and hydrogenating agent in the process. The process can be conducted at room temperature in a suitable organic solvent under an inert atmosphere utilizing the metal alkylamide in stoichiometric quantities. The process is also useful in preparing zero valent Group VIII metal complexes, such as (Ph.sub.3 P).sub.4 Pd.degree..
